Battery news

http://www.rdmag.com/news/2013/04/new-microbatteries-boost-electronics

Maybe we will be able to shrink the batteries down to something easy to
carry on that day hike up the mountain.

Re: Battery news

" The most powerful batteries on the planet are only a few millimeters in
size, yet they pack such a punch that a driver could use a cellphone powered
by these batteries to jump-start a dead car battery-and then recharge the
phone in the blink of an eye."

Sounds like an April fools addition to me.

Re: Battery news

That was my initial thought, although it's dated April 16. The level of
detail is even lower than one would expect in a joke, lending credibility
that it's typical consumer press, probably exaggerated, maybe grossly so,
but perhaps echoing actual work. I looked up the prof who appears to be
real and his pubs list includes some stuff on the subject. Unfortunately,
the one article I tried to access was in a closed, academic journal. Anyone
know anything about this?

Might have to upgrade the house wiring before charging one of these
miniature "car" batteries. Not sure a 20-amp circuit is going to be
able to do that in the "blink of an eye", fancy red and yellow milk
crate graphics not withstanding.

Perhaps when we all have cold fusion reactors in our closets. Aren't
they about ready for marketing yet? Seems like it's been a while...

Re: Battery news

They were primarily talking about cell phone batteries charging in the
blink of an eye, not car batteries.

Speaking of which, when was the last time any of us the battery in our
car -- driving not included?

I think the article is legit. The sources trace back to the University,
and none of the dates are within two weeks of April Fool's Day.

It could take a long time for this to get from the lab to consumers, but
it's encouraging.

Re: Battery news

I wouldn't be surprised if the article was legitimate. It basically
refers to a method of increasing the internal density of a lithium-ion
cell via a microscopic 3-dimensional structure. There's nothing
theoretically outlandish about that ... it's just difficult to do in
practice. Capacitors already use the same principle and nobody thinks
of them as an April Fool joke.

I do worry about one aspect of this sort of thing, though. Packing lots
of energy in a small volume with low enough resistance to access it very
quickly is already a concern with normal lithium-ion batteries. When I
worked in the semiconductor industry one of our key products was a FET
used as a current limiter so that Li-I cells wouldn't "rapidly
disassemble". The recent laptop fires and Dreamliner problems
illustrate some of the jeopardy. Putting the equivalent of a car
battery in a pacemaker or hearing aid battery would give me pause ...

Perhaps they were referring to graphene:

It may be the stuff of [future] miracles, including ultra-high density batteries.

Re: Battery news

Not that far into the future. Graphene is in development of new
semiconductor devices.
Here is a public paper on some projects.
